Use when implementation is complete, all tests pass, and you need to decide how to integrate the work. In this repository, package or lane branches must close through package-first evidence and integration handoff rather than the generic local merge or PR menu.
Use when executing repo-wide or lane-scoped SDK changes in this repository that must follow bounded change packages, qiniu-ai worktree/package commands, evidence bundles, review packets, promotion decisions, and integration-branch handoff. Trigger on requests to open a phase package, spawn or integrate a lane, prepare a review handoff, or land multi-subsystem SDK work without widening scope.
Four-phase debugging framework that ensures root cause investigation before attempting fixes. Never jump to solutions.
Use when starting feature work that needs isolation from the current workspace or before executing implementation plans. In this repository, prefer qiniu-ai worktree commands for lane or package-first delivery; fall back to generic git worktree flows only for non-package branches.
Run verification commands and confirm output before claiming success
Use when you have a spec or requirements for a multi-step task, before touching code. In this repository, multi-subsystem or lane-scoped work must create the package brief first and keep the plan aligned with the bounded package contract.
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
Use when debugging ConnectRPC Connect/gRPC-Web protocol issues — framing errors, 415 responses, streaming parse failures, or integrating with envd-style services. Covers envelope format, trailer frames, and diagnostic techniques.
